IMHO, batteries should not be left on a maintainer continuously. Hook your maintainer to a mechanical lamp timer and charger for about 4 hrs per day.
Everyone has opinions and we all know about the smell. Battery maintainers are just that, made to maintain the batteries during extended periods of non use. I've had batteries last as long as 12 years (boat) and 10-11 years on the trailer. Once the camping season ends, batteries go in the garage on the cement floor, connected to the maintainer full time until next spring.
